I can only point out two things. First the "equivalent " brightness is
not "official" I would say that many are overstated. Also note that CF's
will start off dimmer and slowly brighten up. In my bath I have four CF's
and four incandescent lamps that according to the packages should be equal.
When I turn them on the incandescent are certainly brighter, but after a few
minutes the CF's are brighter. The mix of colors makes for a very good
light since it is somewhere between sun light and tungsten. I also like the
slow ramp up of brightness, especially in the morning when I am not really
ready for bright lights.

The ladies appreciate varied bulbs - different wattages, colors, etc. That
way they can judge their makeup under all conditions likely to be
encountered.
My dentist has two four-bulb florescents above the chair. Each one has a
different type bulb. He says it's easier to spot areas needing attention
with the different colors and wavelengths.

I compare based on lumens. I've also been using the 75 watt equivalents
where I used to use 60 watt incandescents, particularly to accommodate
wife as the cfl's take a few minutes to come up to full brightness. I
still save electricity, which I don't care about, and bill is less,
which I do care about. In bath and powder rooms, I use incandescents as
use is only a few minutes and too short to get full light. In one
powder room and my stall shower, I still have original, 35 year old,
super bulbs.
I had one pair of cfl's I had to relegate to the front porch as they
were too white and glared in the house.

What kind of fixtures are you putting them in? If they are recessed
ceiling fixtures, they could be overheating. CFLs have reduced light
output when temperature is non-optimum. Overheating can also shorten
their life a lot.
By-and-large, CFLs with "Energy Star" logo or of a "Big 3" brand (GE,
Philips, Sylvania) are better than others.
In my experience, the following have a high rate of producing less than
claimed light output:
Lights of America (I only bought 1 since 2001)
Maxlite
dollar store ones
At lower illumination levels, sometimes lowish typical home lighting
levels, a characteristic known as "scotopic photopic ratio" makes a
difference. 2700K CFLs have this figure being lower than incandescents
have. That can largely be fixed by using higher color temperature CFLs.
3500K ones usually work well for homes in my experience. Lowes and Home
Depot carry 3500K spiral CFLs in a range of wattages.
I would advise against color temp. higher than 3500K for most home use -
that can appear stark or "dreary gray".

Home Depot is already selling incandescents that have energy efficiency
high enough to be allowed until 2020. These are Philips Halogena "Energy
Saver". They are more efficient than conventional incandescents, and a
little more efficient than more ordinary halogens of similar wattage
and same voltage, but only about 35-40% as efficient as CFLs.

You say you replaced 75 watt incandesant with 100w Cfls!!!! You dont
know what you are talking about, 100w cfls are GIANT and put out 400w
equivilant of incandesants and cost a crap load, maybe you mean an
equivilant amount which is a 22w Cfl , www.PopularMechanics.com
magazine has a review of cfls to incandesant in the HOME section, its
old, Home Depots cfls have a 9 Year Warranty, [ so keep the reciept]
and are better rated than all , even to incandesant [ by a reviewer]
than incandesant in skin color. A 9 w cfl should equal 40 w
incandesant. a 22w cfl will equal 100 w incandesant, or more. when you
realise an incandesant bulb is just an electric heater, and that 100w
bulbs only actualy puts out 6-8 watts of light will you understand how
antiquated Edisons Heaters [ bulbs] realy are. For every 11 of 100
watt bulbs, you generate about 1000 watts of extra heat, !!! and you
will pay extra for you AC to remove it this summer. Electric
companaies love this, your built in suckerism, stupidity, on
incandesant bulbs. That why mine gives them away for FREE.!! You
pay to cool, and you heat with incandesants , so you pay more to cool.
Evil BS them Fkn Elec cos are. But companies are in business for
profitt.
